the article discusses the concept of progression convergence speed, introducing Euler conversion formula and its progression convergence accleration and the conditions that Euler conversion foumula accelerates the convergence of progression.

Application of Euler formula in design of reinforcement in structure constitution;

This paper presents the accurate calculation formula on the equivalent friction coefficient of V-belt drive by educing V-belt Euler formula and introduces a new parameter: the direction angle of friction.

Using Euler formula of the comlex exponent problems of the rotation-axis in mechanics of materials in coplex plane are derived in complex coordinates to avoid complicated geometrical analysis.

The Application of Euler Equation in The Traction Force's Calculation About Traction Drive Elevator

HT5\"SS]The relationship among number of elements, number of nodes, number of the edges on the boundary and number of close boundaries in the mesh drawing of finite element analysis is infered by a suitable variation of Euler equation.

By using some transfer formulae, we may figure out the control point which is impossible for the surveyors to survey directly in engineering survey.

This paper gives a unified approach to Hsu s two classes of extended GSN pairs in the setting of Hsu-Riordan partial monoid which is a generalization of Shapiro s Riordan group, and moreover Hsu-Wang transfer theorem, Drown-Sprugnoli transfer formula and generalized Brown transfer lemma which display some transfer methods of different kinds of Hsu-Riordau arrays and identities respectively.
